Understanding the TTX22M Coil Rear Shock
The Öhlins TTX22M Coil Rear Shock is a high-performance shock designed for aggressive riders who need superior control and consistency. It is equipped with a dual-flow compression system and an adjustable rebound to tailor the shock to specific riding styles and terrain. The shock’s coil spring is known for its durability and ability to provide consistent performance in a variety of conditions.
This rear shock is designed to be user-serviceable, meaning that, with the right tools and knowledge, you can perform many of the necessary maintenance and service tasks yourself. Regular servicing ensures the shock performs optimally and provides you with the best possible riding experience.
Basic Maintenance of the TTX22M Coil Rear Shock
Routine maintenance for your TTX22M Coil is crucial to ensure its long-term performance. Here are the basic tasks you should perform regularly.
Cleaning the Rear Shock
A clean shock operates more smoothly and is less prone to dirt and debris causing internal damage. Begin by removing the shock from your bike. Using a clean rag, wipe down the shock body and the coil spring to remove any mud, dirt, or grime that has built up during riding. Make sure the eyelet (where the shock mounts to the bike frame) is also cleaned thoroughly.
Lubricating the Shock
After cleaning, it’s essential to lubricate the shock’s seals and bushings. Use a light coat of suspension fluid and apply it to the shock’s moving parts. Ensure that the seals are properly lubricated to prevent dirt from getting inside the shock body.
Step-by-Step Guide to Servicing the TTX22M Coil Rear Shock
1. Removal of the Shock
Before beginning any service, it’s essential to safely remove the shock from the bike. Start by loosening the bolts on both the top and bottom eyelets of the shock using the 10mm socket wrench. Carefully remove the shock from the frame, ensuring not to damage the mounting hardware or the shock itself.
2. Disassembling the Shock
Once the shock is removed from the bike, begin the disassembly process. Using a T25 Torx driver, remove the external compression knob and any other adjustable components on the shock. Be sure to keep track of any washers, o-rings, or small parts that come off during disassembly.
Next, remove the rebound knob using the appropriate tools. After that, use the 17mm socket wrench to remove the shock’s spring retainer. The coil spring can now be removed, giving you access to the inner components.
3. Cleaning the Internals
With the shock disassembled, use a small brush to clean the inside of the shock body. Be gentle to avoid damaging the internal components. Use a clean rag to wipe away any debris and excess suspension fluid.
4. Inspecting Seals and Components
While the shock is apart, inspect the seals for wear. The TTX22M Coil’s seals should be checked for any tears, cracks, or signs of hardening. If the seals appear damaged, they should be replaced to ensure proper performance.
Also, check the shock’s piston and internals for any signs of wear or damage. If any components are showing significant signs of wear, consider replacing them before reassembling the shock.
5. Replacing Suspension Fluid
Drain the old suspension fluid from the shock and replace it with new fluid. Make sure to use the recommended fluid from Öhlins for the TTX22M Coil model. To ensure the shock is properly filled, use an oil pump specifically designed for suspension fluid. Carefully fill the shock with the correct amount of fluid, checking the manufacturer’s instructions for the correct quantity.
6. Reassembling the Shock
Once the shock is clean, the seals are inspected or replaced, and new suspension fluid is added, begin the reassembly process. Start by reattaching the coil spring and tightening the spring retainer with the 17mm socket wrench. Carefully reinstall the rebound and compression knobs, ensuring that all components are secure.
Before mounting the shock back onto the bike, double-check that all parts are properly aligned and tightened to the correct torque settings as specified by Öhlins.
7. Mounting the Shock Back onto the Bike
Once the shock has been fully reassembled, it’s time to remount it onto the bike. Align the shock’s eyelets with the frame and secure it using the bolts you removed earlier. Tighten the bolts to the recommended torque settings to prevent any damage or loosening while riding.
Troubleshooting Common Setup Issues
Even with regular maintenance, issues can arise with your TTX22M Coil Rear Shock. Here are some common problems and how to troubleshoot them:
Problem: Loss of Rebound Control
If you notice that the shock is not controlling the rebound effectively, this could be due to a lack of suspension fluid or an issue with the rebound damper. Check the fluid level and inspect the damper for any signs of damage. If necessary, replace the damper or fluid.
Problem: Unusual Noises
Unusual noises, such as clicking or popping, can occur if there is debris trapped inside the shock or if the seals are worn. Clean the shock thoroughly, paying attention to the seals. If the noise persists, check for any damage to the shock’s internal components.
Problem: Bottoming Out
If your shock is bottoming out too easily, this may be a result of incorrect spring tension or insufficient damping. Consider adjusting the preload on the coil spring or adjusting the compression settings to provide more support. You may also want to replace the coil spring if it’s no longer providing the correct amount of resistance.
Customizing the TTX22M Coil for Better Performance
Customizing your TTX22M Coil Rear Shock to suit your riding style and terrain is essential for maximizing performance. The TTX22M Coil offers several adjustment options:
- Compression Damping: Adjusting the compression damping allows you to control how the shock absorbs impacts. For aggressive downhill riding, increase the compression damping to prevent bottoming out. For smoother trails, you can decrease compression damping for a more plush feel.
- Rebound Damping: Adjusting rebound damping controls how quickly the shock returns after compression. Slower rebound settings are ideal for rough terrain, while faster rebound settings work better on smoother surfaces.
- Spring Preload: Adjusting the preload on the coil spring allows you to fine-tune the shock’s responsiveness to your weight and riding style. More preload can make the shock stiffer, while less preload provides a more forgiving ride.
Compatibility with Other Drivetrain Components
The Öhlins TTX22M Coil Rear Shock is designed to be compatible with a wide range of bikes, but it’s important to ensure that it matches the geometry and performance requirements of your bike frame. Before purchasing or servicing your shock, double-check that it is compatible with your bike’s suspension design and intended use.
Conclusion
Servicing your Öhlins TTX22M Coil Rear Shock at home is entirely possible with the right tools, knowledge, and attention to detail. Regular maintenance, such as cleaning, lubricating, and fluid replacement, will keep the shock functioning at its best. By following the steps in this guide, you can ensure that your shock remains in optimal condition, providing you with consistent performance on every ride.
